“…Such assessments of self-reported drug craving have utility for predicting lapse and/or relapse (Heinz et al, 2006;Paliwal, Hyman, and Sinha, 2008) and are therefore important for researchers and clinicians who wish to assess patient outcomes. Craving assessments have been extended to many substances, including alcohol (Bohn, Krahn, and Staehler, 1995;Flannery, Volpicelli, and Pettinati 1999;Singleton, Tiffany, and Henningfield, 1994), marijuana (Heishman, Singleton, and Liguori, 2001), opiates (Franken, Hendriks, and Van-den-Brink, 2002), nicotine (Cepeda-Benito and Ruig-Ferrer, 2004;Cox, Tiffany, and Christen, 2001;Tiffany and Drobes, 1990;Toll, McKee, Krishnan-Sarin, and O'Malley, 2004), food (Cepeda-Benito et al, 2000), and importantly, cocaine (Halikas et al, 1991;Tiffany, Singleton, Haertzen, and Henningfield, 1993).…”
